Why Does CS-Cart Show Different Shipping Options for Similar Orders?

Two orders that look similar may receive different shipping options because of product dimensions, warehouse assignment, destination rules, customer group, vendor configuration, or carrier service availability. A hidden product setting can affect the package calculation.

What to check

Compare the exact cart contents, quantities, shipping address, selected warehouse, product shipping properties, customer group, and rate calculation logs. Test with a controlled pair of carts that differ in one factor.

Recommended next step

Align product and location data with the intended shipping policy, then validate common order combinations and edge cases. Keep customer-facing explanations accurate when a delivery method is unavailable.
